HOUSTON - April 8, 2009 - The Information Store^® (iStore) and CSC (NYSE: CSC) have signed an alliance agreement under which CSC will act as the prime systems integrator and consulting services provider for iStore's PetroTrek^® Digital Oilfield solution. The parties will team to make iStore's PetroTrek Digital Oilfield solution available under CSC's Petroleum Enterprise Intelligence offering.

Petroleum Enterprise Intelligence enables oil and gas companies to optimize operational performance by effectively managing work processes and information. The solution gives users across the enterprise a consistent decision-support framework, helping connect the right people with the right information at the right time.

The new Web-based solution simplifies how production managers, engineers, and geoscientists, locate and view key technical, operational, and financial information on wells, fields, and reservoirs in the context of their work, saving time and improving their decision-making capabilities.

Petroleum Enterprise Intelligence combines business process management with business intelligence technology, featuring Web-based Key Performance Indicator dashboards that integrate data. iStore's core Digital Oilfield technology virtually integrates multiple, disparate data sources, from commercial data repositories to proprietary systems and unstructured data. CSC's solution extends the Digital Oilfield by adding business intelligence functionality, as well as enabling optimization through modeling, planning, and analytics.

iStore and CSC are teaming to develop and deliver the solution worldwide. As a global leader in providing technology-enabled solutions and services, CSC opens new distribution channels and opportunities for iStore's software products and technology.
